- GASOLENE FILTER OR TRAP.

Specification of Letters Patent.-

Patented Apr. 21, 1914.

Application filed June 30, 1913. Serial 110.776,?11'.

To all whom it may. concern:

Be it known that I, JAMES H. FINGH, J r., a citizen of the United States, residing at Quincy, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements-in Gasolene Filters or Traps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyiiig drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in gasolene filters or traps for automobiles, mOt-Or boats, etc., designed to be applied to the fuel pipe between the tank and carburetor and adaptedto catch water or other foreign matter which may be contained within the fuel, thereby cleansing the latter before passing to the engine.

The invention comprises varlous details of construction and combinations and arrangements of after fully described, shown vin the accompanying drawings and then specifically defined in the appended claims. I

I illustrate my invention in the accompanying drawings, in which Figure 1 is a central longitudinal sectional view through a filter made in accordance with my invention, and Fig. 2 is a cross sectional view on line 2-2 of Fig. 1.

Reference now being had to the details of the drawings by letter, A designates a cylindrical open-ended shell, preferably of glass, and B and B designate metallic heads, each recessed upon its inner face and adapted to receive the ends of the washer C and again'st which the ends of the cylindrical shell A bear. Screws, designated by letter E, pass through registering apertures in the heads, thew threaded ends of the screws engaging threads formed in one head and serving as means for holding the parts securely together.

The head B has a central exit opening F about which a boss F projects, said exit opening F being adapted to be connected to a carburetor or vaporizer not shown. The opposite end B has an inlet opening H for connection to a supply tank, not shown. A filter member formed in the shape of a bag is provided and whichis designated by letparts which will be hereinter N and has its open end fitted over said boss, a coiled spring 0 being mounted within the filter and telescoping over the boss and serving to hold the filter bag, which is made preferably of chamois or any other suitable material which mightbe well adapted for the purpose. The headB' has a duct S leading therethrough and communicates with a drainage cock T, whereby water or any foreign matter may be conducted away from the reservoir.

F astened to the inner surface of the head B is an inverted V-shape water or foreign matter shedding member S which covers the duct S and which is provided for the purpose of causing water or other foreign matter in the gasolene or kerosene to flow out through the valve-regulated duct before the passage of any gasolene therethrough, the pressure of the gasolene or other fuel being adapted to force the foreign matter out of the-reservoir.

By the provision of a filtering device embodying the features of my invention, it will be noted that the chamois skin or other filtering covering will be held in shape by the coiled spring, pressure of fuel or water which may flow into the reservoir at the end opposite the.

outlet.

What I claim to be new is 1. A filter for fuel comprising a reservoir having ends with inlet and exit openings and a valve-regulated drain duct, a filter of chamois skin or other fabric inside the reservoir and about the exit opening, a spring mounted within said filter and a foreign matter shedding de'vice positioned underneathsaid fabric and over the valve duct, as set forth.

2. A' filter for voir having ends with ings and a valve-regulated. drain duct, one end of the reservoir having a boss, a filter bag closed at one end and at its open end fitted over said boss, a spring mounted within the filter bag and holding the latter a ainst said boss, and a foreign matter sheddlng device positioned underneath the filter bag and over the valve regulating the duct, as set forth.

3. A filter for fuel comprising a reservoir having ends with inlet and exit openings and a valve-regulated drain duct, one end of the reservoir having a boss, a filter bag closed at one end and at its open end fuel comprising a reserinlet and exit openserving to receive any extra fitted over said boss, a spring mounted within the filter bag and holding the latter against said boss, and aninverted troughshaped shedding device fastened to one end of the cylinder, over the valve-regulated duct and underneath said filter bag, as set forth.

4. A filtering device for gasolene and other fuel comprising an open-ended cylindrical shell, end sections which are recessed upon their inner faces, packings seated in said recesses against which the ends of the shell are adapted to contact, screws for holding the heads against the ends of the shell, one end of the shell provided with an inlet opening and the other with an outlet opening and valve-regulated drain duct, a boss projecting from the inner face of one'head about said exit opening, a filter bag of chamois or other suitab material telescoping over said boss and closed at its opposite end, a spring within the filter bag, and a foreign matter shedding device projecting from one of said ends and posltloned underneath the filter bag and over said duct, as set forth.

In testimony whereof I hereunto afiix my signature in presence of two witnesses.
